You have a heating/cooling curve assign due on Tuesday of next week Find the total energy required to cool ethanol from 102 degrees C to -134 degrees C The Volume that you are cooling is 500mL. Show your work and units for all five calculations for the cooling curve. The bp= 76oC mp= -114oC. Circle or highlight the values that you obtained from tables. The specific heat values for ethanol steam is 0.85 J/g oC and frozen ethanol is 1.05 J/goC. The value for the liquid can be obtained form your table 17.1. The value for Hvap= 38.56KJ/mol and H fus=4.90KJ/mol (2011 data). Please include a well-labelledcooling curve with PE, KE, formulas and states on it. Your final answer should contain the proper number of significant digits.
Lab Set One
Lab 1/5 Metric lab-This lab involves working with measurement of area, finding the density of a shape and some challenging conversions
Lab 2/6 Elements versus Compounds-This experiment involves using heat to break down compounds. You will find that it has a flaw in terms of trying to break down all compounds. You will become an expert at using the centigram balance.
Lab 3/7 Candle Lab-This lab involves making observations and trying different techniques for dealing with candle wax combustion.
Lab 4/8 Separation of Matter-This experiment involves using the various methods for separating matter to separate the components in an unknown mixture. Accuracy will be very important in this experiment

You have a heating/cooling curve assign due on Tuesday of next week
Find the total energy required to cool ethanol from 102 degrees C to -134 degrees C The Volume that you are cooling is 500mL. Show your work and units for all five calculations for the cooling curve. The bp= 76oC mp= -114oC. Circle or highlight the values that you obtained from tables. The specific heat values for ethanol steam is 0.85 J/g oC and frozen ethanol is 1.05 J/goC. The value for the liquid can be obtained form your table 17.1. The value for Hvap= 38.56KJ/mol and H fus=4.90KJ/mol (2011 data). Please include a well-labelledcooling curve with PE, KE, formulas and states on it. Your final answer should contain the proper number of significant digits.

Lab Set One
Lab 1/5 Metric lab-This lab involves working with measurement of area, finding the density of a shape and some challenging conversions
Lab 2/6 Elements versus Compounds-This experiment involves using heat to break down compounds. You will find that it has a flaw in terms of trying to break down all compounds. You will become an expert at using the centigram balance.
Lab 3/7 Candle Lab-This lab involves making observations and trying different techniques for dealing with candle wax combustion.
Lab 4/8 Separation of Matter-This experiment involves using the various methods for separating matter to separate the components in an unknown mixture. Accuracy will be very important in this experiment
